21.  On 20 January 1998 the Nitra Regional Court upheld the District Court’s finding that the applicant was not entitled to compensation for the proposal in question as it was neither genuine nor did it resolve the technical problem in question as required by the relevant law. The Regional Court further discontinued the proceedings as regards the applicant’s claim that his proposal should be given priority as it was outside the courts’ jurisdiction. Finally, the Regional Court upheld the District Court’s decision on the expert’s fees and decided that the District Court judge involved was not biased. The Regional Court’s judgment was served on the applicant on 4 August 1998.
